Cancun offers more than the expected Mexican restaurant standards, though it still has the ever-popular burritos, tacos, and quesadillas. Thrown in among the favorites are a few dishes that raise Cancun out of Taco Bell territory, like the tostada de ceviche, a fresh combination of shrimp, lime juice, salsa, and avocado. Reflecting its namesake’s coastal location, seafood pops up in unexpected places, putting a new spin on classic dishes like shrimp, scallop, and crab fajitas and the crab and shrimp chimichangas and enchiladas. Nopales, the juicy prickly pear stems, make a cameo in several dishes and add a little authentic flavor.
